NASA Software Raises Bar for Aircraft Icing Research

When flying in certain weather conditions, tiny freezing water droplets floating in the air can pose a risk to aircraft. If not taken into consideration, these water droplets can accumulate on an aircraft as ice and pose a safety risk. But NASA software tools such as Glenn Icing Computational Environment (GlennICE) are working to keep […]
